Listed at 17 retailers as of October 27, 2026, with prices from $767 to $8,683, a $7,916 spread on the same certified stone. Brilliant Earth lists it at $8,683. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
